4. David Fales, San Jose State

David Fales isn't much bigger than Manziel but he's much more of a pure pocket passer.

He can move around in the pocket to avoid pressure and occasionally squirm free to pick up some yardage on the ground, but the San Jose State star won't be running often.

Fales wins with a strong arm, polished downfield touch and sound footwork in the pocket. Also, he showed a capacity for reading more than half the field. Rather, he regularly scanned the defense and still got the football out on time.

He could use some coaching, as his lower half doesn't appear to generate the torque necessary for throwing the ball with velocity.

4a. Derek Carr, Fresno State

Derek Carr's monster arm is the first attribute that stands out about him. He can change arm angles to fit the football through tight windows to his receivers.

Carr needs to improve his footwork, as he can get a little jumpy in the pocket when his first read isn't there. But for the most part at Fresno State, he showed he was quite capable of reading coverages.

At 6'3'', he's not undersized by NFL standards, and he throws the football accurately to every level of the field.

If there's any worry about Carr, it's that he wasn't always comfortable when dealing with pressure and blitzes.

6. Tajh Boyd, Clemson

Tajh Boyd is a smaller, athletic quarterback with a decent arm and loads of collegiate experience.

He made a considerable jump as a passer over his three final seasons at Clemson, though the Tigers in his senior season fell somewhat short of lofty expectations.

At 6'1'' and 225 pounds, Boyd is a good runner—even inside—and is very familiar with the read-option.

Although he's pretty athletic, Boyd often got flustered in the face of pressure, which led to many bad decisions and ill-advised throws.

When given a clean pocket and time to scan the defense, he did show some nice touch downfield. Given that touch, along with his mobility, the Tigers standout could be an efficient passer on a team that utilizes a West Coast offense.
